That "II" chamber isn't even a good idea for micro action bolt guns because most of their magazine length restrictions don't allow that long of a COL.
Why anyone would think of it for use in the AR15 continues to baffle me, unless you're single loading.
I've shot multiple 5rd and 8rd groups with many different SAAMI chambers into the .3's through .6's. I've never seen the excessive freebore chambers come close to that.
